Predicting photosynthesis and transpiration responses to ozone: decoupling modeled photosynthesis and stomatal conductance

Plants exchange greenhouse gases carbon dioxide and water with the atmosphere through the processes of photosynthesis and transpiration, making them essential in climate regulation. Carbon dioxide and water exchange are typically coupled through the control of stomatal conductance, and the parameterization in many models often predict conductance based on photosynthesis values. Some environment...

Interactive comment on “Predicting photosynthesis and transpiration responses to ozone: decoupling modeled photosynthesis and stomatal conductance” by D. Lombardozzi et al

This manuscript continues previous work to address the issue of ozone exposure affecting leaf photosynthesis and conductance differentially and how this can be addressed through modifications to the Farquhar/Ball-Berry model. Specifically, the authors consider the implications of these effects when taken into account in a terrestrial ecosystem model. This issue is critical to understanding how ...

Second, for every cm of rainfall, the free Sugarcane (Saccharum spp.) is the primary crop on the Histosols water in the soil profile of EAA Histosols can be exof the Everglades Agricultural Area (EAA), where periodic floods pected to rise about 10 cm (Glaz et al., 2002). Finally, and undesirably high water tables are increas...
